Is the source sent from CPU to GPU without adding or deleting anything?

Hi developers,

Does the host (CPU) side modify the source code before

it is sent to GPU to be executed with clCreateProgramWithSource ?

For example, will program comments be sent from CPU to GPU ?

thanks in advance !

of cource. it must compile just like any other source code into executable binary.

clCreateProgramWithSource generally creates a program object which is used by cl compiler. The program object is compiled by clBuildProgram. The comments would surely be ignored at this stage.

Hi Nou,

Yes, a source program gets compiled without comments.

Therefore CPU did not have to send comments to GPU but

instead it could send a source without comments.

Q1.

Are comments being sent to GPU ?

Q2.

Is a source sent from CPU to GPU as it is without any modification ?

Q3.

Will the GPU compiler receive a source exactly as it was sent by CPU ?

thanks in advance

no whole compilation is done on CPU. what GPU get is this

and of course compiler will get whole source code. if you are interested in hide your code then dont ship kernel code at all.

Hi Nou !

We embed some stuff as comments in source files and

just wanted to be 100% sure.

THANKS !
